With the rapid development of Software-Intensive System (SIS), equipment software system plays more important role in new-generation weapon. The current development of equipment software is summarized. In order to improve the safeguard capacity of equipment software and form complete and comprehensive safeguard architecture, the key input and output factors of estimation model for equipment software is established. According to the standard of ISO/IEC 12207, the whole life cycle of equipment software is divided into three different processes and corresponding activities in three processes are defined in detail. Aiming to the blindness of equipment software's transplant and retirement, the activities in transplant and retirement processes are emphasized. Possible changes and the corresponding works in equipment software's whole life cycle are also defined. Finally, the means to enhance the level of equipment software support for such conceptual change, regulation and system and talents training are discussed. [ABSTRACT FROM PUBLISHER]

The repair quality of ordnance equipment affects directly fighting capacity of equipment. Therefore, it is necessary to study repair quality control of equipment. In light of modern mathematical statistics principles, we do analysis and systematic research on the quality data obtained in a factory so as to identify improvement measures, thus promoting repair quality control standard of ordnance equipment.

Transmission system is the key subsystem of Complicated equipment to realize its maneuverability. Statistic data show that 36 percent of chassis faults is caused by transmission system. To overcome the difficulties of battle decision in confirming appropriate maintenance periods and allocating maintenance resource, a new kind service life and evaluation method based on virtual prototype and Finite Element Analysis (FEA) is put forward firstly. The three-dimensional solid models of transmission system is established and assembled in Pro/E. By adding relevant forces and constraints, the working and fault emergence and development processes are simulated in MSC.ADAMS. The FEA models of key components are established in MSC.Patran and FE-FATIGUE. On the basis of simulation results of virtual prototype and FEA analysis results, the service life of key components of transmission system can be calculated. [ABSTRACT FROM PUBLISHER]

Modern self-propelled artilleries compose weapons parts and chassis parts. Its chassis is walking part of self-propelled artilleries and the chassis engine is the heart of the walking part. Technical state of the engine directly influences the condition of artillery technology. Thus, the research on fault diagnosis of the chassis engine of artilleries is very important. Fault diagnosis of the engine of artillery chassis based on gas pressure are analyzed and researched in this paper. [ABSTRACT FROM PUBLISHER]
